Losing grain over walkers. All properly threshed out just not being seperated.
Anyone any pointers as quite a novice combine driver???
Thanks

What are you combining? Never had a big problem with losses over walkers. Mostly sieve loss is limiting factor or power

In cereal move the lever ahead/closed position on right side beater concaves. Might not be pushing through the concave fast enough and its overloading the walkers.

Might have to slow down a bit.

almost always this issue can relate to not enough air at the front end of the seive/chaffer . you need to get the mat of material floating on air so that it can separate by gravity. not very often have i seen too much air, but it definitely needs to be directed to the front to get the floatation happening.

Is your rotary separator in high and the separator concave closed? You don't have your curtain tied up by any chance or it hasn't gone missing? There's a chain under the engine oil pan that should be loose. It ties up that curtain. Rotary separator speed is adjusted on the right side, belt needs to be on the large drive sheave and smaller driven sheave. What was this machine setup to harvest before?

The rotary separator is closed and on the fast setting. The straw curtain is down also. How fast should the drum be going? And what gap? Is it better tho thrash more to try to remove it from the straw?

In wheat as fast as it will go and about 1/2-3/4" for concave depending on moisture and type of wheat. Not really a problem in wheat but in barley you can over thrash and load up the sieves. The cx in wheat is a beast. Power is always limit for us in it

How about your awning plates under the concave, are they both open? That would drive more grain up onto the walkers.

Out of curiosity, how are you determining loses over the walkers? If you are relying on the monitor only you might have to adjust the sensitivity. Best way is to capture samples and sift through them. These machines don't have a tendency to throw over the walkers as stated above.

Not got the concave plates in. Losses are checked by shaking straw out.
Meskie, do you have raisers on your walkers???

Does slowing the shoe speed on the left side slow the walkers too? It should be in high speed anyway.

Try opening your beater concave wide open , walker risers I believe aren't going to help too much . Large volumes of of straw need a big opening , the main cylinder will separate , but you need to let the grain get out of the mat of straw , .This may sound to go against logic , but have u tried increasing ur forward speed.
